Struct smartnoise_runtime::proto::Quantile

pub struct Quantile {
    pub alpha: f64,
    pub interpolation: String,
}

Quantile Component

Get values corresponding to specified quantiles for each column of the data.

This struct represents an abstract computation. Arguments are provided via the graph. Additional options are set via the fields on this struct. The return is the result of the quantile on the arguments.

Arguments

• data - Array - Atomic type must be numeric.
• candidates - Array - Set from which the Exponential mechanism will return an element. Type must match with atomic type of data. This value must be column-conformable with data.

Returns

• Value - Array - Quantile values for each column.

Fields

alpha: f64

Desired quantiles, defined on [0,1]. Examples: 0: min, 0.5: median, 1: max

interpolation: String

Interpolation strategy. One of [lower, upper, midpoint, nearest, linear]

impl Default for Quantile

pub fn default() -> Quantile

Returns the “default value” for a type.

impl Evaluable for Quantile

fn evaluate(
    &self,
    _privacy_definition: &Option<PrivacyDefinition>,
    arguments: NodeArguments
) -> Result<ReleaseNode>

The concrete implementation of the abstract computation that the struct represents.
